bolt. It. is eARpec-iully useful for scouring rails to concrete railway ties.

.In the accompanying drawing, Figure l is a broken IOW'ilUtlillRl semi-rm of a concrete nving my device cudwddcd therein and showing the rail in'crcFs :svctiun: Fig. 2 is a cross section of the sainc through the enlarged central chamber; Fig. 3 is 11 Phil! View of the device detached; Fig. 4 is an cud view thcreof; Fig. 5 a pianiviow.

it ef'crring to the drawing, 1 maii-"iites a concrcte railway tie in which my imp'rovvd device is cmhcdded, and 2 indicates A rail laid on the top of said tic. It '5 to be'undcrstoud that, while the device is here snown as cmbcddcd'in P. concrctc railway tie, it. can also be used in other masonry cousin: Lions.
